Nephrogenic systemic fibrosis is a severe disabling disease that can follow gadolinium-based contrast exposure. In this study we analyzed the clinical and laboratory records of patients with nephrogenic systemic fibrosis who had a history of exposure to gadolinium-based contrast media and identified their cardiac and vascular events. At autopsy, we found that the heart, blood vessels, and skin of three patients who died of cardiac and/or vascular complications had appreciable amounts of gadolinium, iron, and aluminum as measured by inductively coupled plasma-mass spectrometry and confirmed by x-ray fluorescence. Of the 32 patients with nephrogenic systemic fibrosis studied, 10 died at a median of 112 days after diagnosis. Cardiovascular events contributed to the mortality of 9 patients and included congestive heart failure, recurrent arrhythmias, hypotension, stroke, limb ischemia, posterior ischemic optic neuropathy and sudden death. Our results show that increased cardiac and vascular complications along with short survival in nephrogenic systemic fibrosis are associated with metal accumulation in the heart, blood vessels, and skin of these patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
